Why do men wear beard oil

Men wear beard oil mainly to condition the beard hair and moisturize the skin underneath it.

A good beard oil can:

Soften coarse beard hair and make it feel smoother.

Reduce dry, itchy skin underneath the beard.

Help prevent beard dandruff/flaking caused by dry skin.

Improve manageability, making the beard easier to comb and style.

Reduce the rough, brittle feeling that can lead to breakage and split ends.

Add a healthy-looking sheen without making the beard look greasy when used correctly.

Improve the overall appearance of the beard by helping hairs lay more uniformly.

Add fragrance, depending on the product.

The important distinction is that beard oil isn't really about making a beard "oily." A well-formulated beard oil is essentially a leave-in conditioning product for both facial hair and the skin beneath it.

And that's why the carrier oils matter so much. Different oils can emphasize skin conditioning, hair penetration, softness, shine, oxidation stability, or a dry/non-greasy feel.
